1-Hexadecanethiol is a chemical compound from the group of thiols. Its chemical formula is C
₁₆H
₃₄S.^[1]^[2]

Synthesis edit

1-Hexadecanethiol can be obtained by reacting 1-bromohexadecane with thiourea.

Properties edit

1-Hexadecanethiol is a combustible colorless liquid with an unpleasant odor, which is practically insoluble in water.^[3]

Applications edit

1-Hexadecanethiol is used as a synthesis chemical. The compound is also used for the production of nanoparticles and hydrophobic self-assembling monolayers. The high affinity of the thiol group to the elements of the copper group causes the thiols to spontaneously deposit in a high-order layer when a corresponding metal of a 1-hexadecanethiol solution is exposed.^[4]

Toxicology and safety edit

The substance decomposes upon combustion with the formation of toxic gases, including sulfur oxides. It reacts violently with strong oxidizing agents, acids, reducing agents, and metals.
